The Girls Aloud babe reckons she’d be perfect on Simon Cowell’s singing contest because she’s been through the whole process herself.

Sarah, who has had a tough few years battling booze addiction and depression, believes a move into telly could become a reality.

She told the Daily Star a slot on the X Factor “would be good”, adding: “I’d consider it, definitely. I would love to be a mentor.

“If I feel someone has talent and potential I can always see it in them. I’d love to do that.”

Sarah, who shot to fame with Cheryl and the rest of Girls Aloud on Popstars: The Rivals in 2002, admits The X Factor boss Cowell, 53, has yet to contact her for a tryout – possibly because Cheryl, 29, has already been on the panel.

The 31-year-old checked herself into rehab following her split from her DJ fiancé Tom Crane in September 2011.

She was also involved in a New Year’s bust-up with then boyfriend Theo Van Dries and just last week was banned from driving for using her phone at the wheel.

Now she is keen to move into telly after admitting she was a “little bit lost” when Girls Aloud announced they were splitting up earlier this month.

She said: “It’s like: ‘Eeek I’m on my own now.’ But I already had things in the pipeline.

“It’s a little bit weird, I’m used to having four other girls with me. It’s a bit nerve-wracking at first. They’re like your sisters.”
